 Left: Excess dielectron p2T,ee-differential yields after subtraction of the cocktail of known hadronic decay contributions in peripheral (70–90%) Pb–Pb collisions at √sNN = 5.02 TeV for different mee ranges, i.e. 0.4 ≤ mee < 0.7 GeV/c2, 0.7 ≤ mee < 1.1 GeV/c2 and 1.1 ≤ mee < 2.7 GeV/c2, compared with calculations for coherent photon–photon production of dielectrons folded with the detector resolution [21, 24, 28, 36, 84]. Right: Excess dielectron p2T,ee-differential yields after subtraction of the cocktail of known hadronic decay contributions in peripheral Pb–Pb (70–90%), Au–Au (60–80%) and U–U (60–80%) collisions at √sNN = 5.02, 0.2 and 0.193 TeV [12], respectively, in a similar mee range. The error bars and boxes represent the statistical and systematic uncertainties of the data, respectively. Arrows indicate upper limits at 90% confidence level
